How to make rainbow soap?

Sometimes you want to make a few special soaps to offer as gifts or to fill the little basket in your guest bathroom. A good way to give your imagination free rein and create a work of art is to take advantage of the simplicity of glycerin soaps. To learn more about glycerin soap, click here.

To have some fun with colours, we decided to show you a layered soap reminiscent of a rainbow – both the one in the sky and the one on the gay pride flag.

A few tips and tricks

  • Begin by assembling all the tools and ingredients needed to make the soap.
  • Next read the recipe to the end so you understand all the steps.
  • This is an intermediate-level recipe. We encountered a few problems when testing it, particularly with the layers separating when we went to cut the soap, so follow the instructions carefully. We’ve carefully explained what to do and offered some tips and tricks for making a perfect rainbow!

Important tips to ensure success!

    • Before pouring a melted layer over a hardened layer, spray the hardened layer again with alcohol (about 6 pumps). This helps the layers to stick to each other.
    • When pouring the layers of melted soap over the layers of hardened soap, use the spatula to keep them separate. Hold the spatula at an angle near the surface of the soap in the mold and pour the hot, melted soap onto the spatula. Then use the spatula to gently spread the melted soap over the hardened soap to ensure it is evenly distributed. Click here to see an example from another recipe.
    • The exact cooling time is important. If you don’t wait long enough, the soap will be too soft to be unmolded, and the layers could separate. If you wait too long (such as overnight), the layers will be too fragile, and the outside layers could crumble when the soap is cut. Also, don’t try to speed things up in the refrigerator. The layers could cool at different rates and separate.

Steps to follow

  1. Prepare and sterilize your equipment and workspace.
  2. Use the knife to cut the blocks of glycerin soap into cubes.
  3. Melt them in the double boiler (cover the pot or bowl).bain-marie
  4. While the soap is melting, add the above amounts of the six colorants to the six bowls.
  5. Arrange the bowls containing the colorants in this order: mauve, blue, green, yellow, orange, red.Colorants pour savons à la glycérine
  6. Place the essential oils and the aromatic essence in the ramekin.
  7. When the soap is completely melted, add the mixture of essential oils and aromatic essence and mix well. Keep the double boiler covered and heated (50 to 55 degrees Celsius) to prevent a film of cooled soap from forming on the surface of the mixture.
  8. Place the bowl containing the first colour (mauve) on the scale and add 150 g. of the melted soap mixture.
  9. Use the spoon or the mini mixer with the wheel attachment to quickly blend the melted soap with the colorant (avoid creating foam).
  10. Pour this first layer of colour into the rectangular mold, using the spatula to remove all of the melted soap from the bowl.
  11. Immediately spray the layer of soap with the alcohol (about six pumps) to eliminate bubbles. Allow to cool and solidify for about 13 minutes. Be sure not to leave it too long.
  12. Once the top of this layer is firm but not completely cooled, continue with the second colour (blue), repeating steps 7 to 10. But before doing so, read the following tips.
  13. When all the layers have been poured, let harden for one and a half to two hours.
  14. Your soap is now ready to be cut! Here again, we discovered a trick. To ensure the layers stick together, slice the soap this way:
  15. Turn the soap upside down, with the mauve layer on top. Using the knife and the ruler, make small notches at the edge of the soap, one inch apart.
  16. Then turn the soap over (mauve side down) and repeat. This will enable you to cut straight lines and make eight equal bars.
  17. Now place the soap on its side, so the layers are perpendicular to your knife. Otherwise, the layers could separate! Using the notches on the mauve surface, gently slice the soap along the line.trancher
  18. Use, give away, or display!
